The separate Perplexity result measures whether Copeland's website appeared in the source list returned with a Perplexity Sonar answer. We compared the same 16 questions and counted each list once when an exact Copeland website hostname appeared, regardless of the number of links. The count rose from 2 of 16 to 8 of 16, or 12.5% to 50%. Eight divided by two is four times as many source lists. Initial checks ran from April 21 to July 24, 2026; latest checks ran from September 5 to 21.
Five of the eight latest source lists also had a corresponding citation marker in the retained answer text; three had the website in the source list only. Earlier source records lacked the later citation classification, so the two initial website sources were manually verified against answer citation markers.

Source-list inclusion does not establish a named recommendation, a click or a consumer search impression.
